Lu Xuanping also went out to help those forces that had defected to the Lu family to set up some protective measures. In fact, the coming of the undercurrent was a traditional event in the Endless Dark Sea, and the mortals were gathering in an orderly manner.

The undertow usually passes in three to five days. When the undertow passes, the surging sea water turns into mist that corrodes people's spirit. It can be said to be a very painful disaster.

But at the same time, the reason why immortal cultivators can rule over mortals is precisely because they have this kind of magic array to defend against the dark sea tides, otherwise they would have no legal system to rule.

Fortunately, the flag of this magic array is extremely cheap and easy to use. However, in Lu Xuanping's opinion, although the materials of this magic array are simple, the difficulty of refining is probably extremely high. It only takes spirit stones to buy a flag that can be used for seven days.

Being able to sell it at such a cheap price, it is obvious that the seller does not care about the spirit stones.

Moreover, the method of refining the flag is definitely above the third grade. Even Lu Xuanping cannot identify the refining technique. Although it is not known which powerful person developed it, it is obvious that the other party does so because he sympathizes with the mortals living in the endless dark sea.

You should know that the dark tide does not pose a big threat to cultivators. It only weakens their spiritual consciousness. But for mortals, a big dark tide can cause them to lose ten years of life. If they are old, they will die directly because too much essence has been plundered.

As for the reason for the formation of the undercurrent, Lu Xuanping did not know, but it was related to a myth.

Legend has it that in ancient times, the Endless Sea was located to the east of the continent, with boundless water extending to the end of the world. The sea water was not dark like it is now. Moreover, there were no living creatures in the Endless Sea, no islands, no fish or shrimps, and no monks.

Until one day, a man was born on the continent. He was a murderer and had a broken army star destiny. He committed endless killings. A powerful man wanted to take action to eliminate this evil for the people, but it turned out that the man was protected by the luck of heaven and earth and could not be eliminated at all.

So the mighty one cut down the stars in anger, ending his life and then cut it off, thus removing a great harm from the world.

However, after the star was cut down, it fell into the endless sea with boundless power.

The stars fell, scattering countless fragments, which smashed into the endless sea to form islands, and the main part of them smashed into the present Eastern Region. Because the East China Sea is the main body of the stars, the practice in the East China Sea is the most prosperous.

Moreover, because there is majestic solar true flame above the stars, the sea water comes into contact with the solar true flame after falling, stirring up fog all over the sky.

But the Endless Sea is said to have no end, and eventually the endless water extinguished the true flame of the sun on the stars, and part of the water in the Endless Sea also turned dark permanently, but the unwilling resentment of the stars eventually formed an undercurrent.

The polluted part turned into an endless dark sea, and the unpolluted part was the original endless sea. It was the islands brought by the falling stars that allowed living beings and practitioners to flourish in the endless sea.

However, Lu Xuanping felt that this myth was not correct, and no one would completely connect the myth with reality.

Because the content of this myth is very strange. It says that the islands in the Endless Dark Sea are formed by star fragments. However, Lu Xuanping knows that the islands are not formed by star fragments at all, but by the movement of earth veins.

As for the prosperity of the immortal cultivation world in the East China Sea, it is because they have to fight against the sea creatures in the Endless Sea. It is a place where wars are fought all year round and it has the most resources and cultivators.

In myths and legends, there are no humans or fish or shrimp living in the Endless Sea. However, Lu Xuanping knows that even in the Endless Sea ruled by the sea clan, there are not only fish and shrimp but also sea clan. This shows that the myths are not true.

However, the myth is also adapted from part of reality. This myth also explains that the Endless Sea is divided into two parts. Among the two parts, the main human forces are in the Endless Dark Sea, and the other part is the Endless Sea, where there are no islands on the sea surface and various sea creatures live there that are hostile to humans.

Ordinary Dark Sea waters do not have the ability to corrode human spirit. Instead, it only has this ability when a Dark Sea storm occurs. The bigger the storm, the stronger its ability to corrode human spirit. It is precisely because of these abnormalities that these myths were born.

Lu Xuanping was busy again. Whether this myth was true or not was not important. What was important now was that Lu Xuanping was busy setting up a protected area to protect the mortals and then gather them. When Lu Xuanping was done, he had to rush back to the family to strengthen the defense of the Lu family. After all, when the dark tide came, the spiritual awareness of the cultivators would be weakened to a certain extent, and it was very likely that they would not be able to detect the external enemy.

The Lu family is no longer the original foundation-building family and can only be trapped on an island.

Now that they have become a Jindan force, their territory has expanded a lot. Many places have already joined the Lu family and hung up the Lu family's flag. They regard the Lu family as their master. Naturally, the Lu family needs some help at this critical juncture.

Lu Xuanping went back and forth to look after the mortals, and even the construction of the cave was temporarily delayed.

More than 20 days later, Lu Xuanping looked at the simple living area being built and nodded.

In front of him was a huge crowd of people, a sea of ​​black. He had gathered most of the people on the island here.

There is an underground protection formation on the Lu family's main island that can protect the entire island, but there is no such formation in other places. He can only say sorry. After all, one can only do what one is capable of.

"All the immortals are here." A man dressed in gorgeous silk stepped forward and saluted.

"Um."

Lu Xuanping raised his hand and took out five formation flags and inserted them into the five corners of the temporary camp, and then activated the formation.

There is no wrong version in the 1619 book forum!

The invisible isolation shield will isolate the dark tide's ability to steal people's energy.

"This formation can last for seven days, after which the formation flag will break and disappear."

"Lu Xie, you stay here and watch over them for the time being."

Then Lu Xuanping threw him ten spirit stones and three talismans.

"Yes, Master Xuanping."

Lu Xie and Lu Xuanping are only distantly related, and his cultivation has barely reached the fifth level of Qi training. He is also old, so he was sent out to take care of these mortals.

This island is the farthest one of the Lu family's influence, with a total of about 200,000 mortals. These mortals live on the endless dark sea and have been educated in this way since the day they were born. They have become accustomed to this way of survival and no trouble has occurred.

The tenacity of life is fully demonstrated at this moment.

Although Lu Xuanping is not in the Lu family, the clan leader has recalled some of the foundation-building warriors, so half of the family's combat power will be retained, so the clan is not empty.

Because he learned from Lu Xuanping that the man from the Demonic Path had escaped. When he and Mu Fengsheng went on adventures at sea before, he naturally experienced a lot, and of course he knew what kind of morality the Demonic Path was, and he would never let go of any grievances. How could the other party not retaliate after suffering such a great injustice?
